These objectsI accomplish yin the manner illustratedv in the accompanyllng draw1ngs,'m whichf Figure 1 1s an inner face view. of a doorframe and'one of my improved doors therein.

lSimilar' numeralsfreferj to similarparts throughout the several views.` f f In carrying out my invention I employ a double-dodr construction which comprises an outer door-body l'and an inner `door-body being normally parallel one with the other and separated by a. suitable interspace, as shown. As'i-ndicated' inthe 1 is adapted tohave hinged, as indicated post4.'

At desirable may be connected -bycoiled or other. springs 15, and in order to limit the separating movement. of said doors the same may be-,conne'cted, as-indicated at 16, "by a chain or other equivalent connecting device.

While in the construction shown no means I are disclosed for unlocking the door from lthe outer side, it Will be understood that any well-known or desirable means may be einployed for throwing the bolt from the outer side of the door b lthe employmentof a key or other suitable evice.

It will be observed that a door constructed as described and possessing the advantages set forth Will be of. eat utility in ltheaters and other public bui dings and that' such instructions as Fire exit, Push, &c., may be printed on the door or adj acentthereto.

It is also to be observed that by positioning the doors so that their exterior surfaces lie iiush with the outer and'innersides of the door-frame a practically-smooth surface or Wall is provided both inside and outside of the structure. Inlthis. manner the number of doors or exits may be increased Without l marring the appearance or symmetrical eff'ect of the structure for the reason that by causing the said doors lto lie flush with the Walll in which they are supported recesses or projectionsare obviated, and while the doors are 'readily perceptible thev general 'interior decorations and pleasing finish are not affected i andthe Wallsl are giver. a solid appearance.

Having now 1r'ully described my invention, what I claim, and desire to secure by Letters Patent, is A 1. In a 4{ire-exit door, the combination with a door-frame, Aan outer door hinged therein, an inner door hin ed to the outer door, of a sliding locking-bo t carried by the outer door, a bracket supported from the outer door, a lever pivoted in the bracket having one end in contact with the bolt and the other end bearing against the inner door, and means for connecting the doors.

2. In a fire-exit door, the combination with adoor-frame and an outer door hinged therein so as to lie flush with the outer side of the door-frame, of an inner door completely filling and lying flush with the inner side of the door-frame and supported from the outer door so as to provide a substantial space therebetween, the said inner door being hinged to the outer door so as to swing in the full half of a circle out of the door-frame with the outer door and in the same horizontal plane, and locking means for the outer door, operated by the inner door, arranged in the space between the doors.
